As shown in fig. 1 and 2, in the present embodiment, it is exemplarily illustrated that the housing 100 may be provided in a circular tube shape, both ends of which are open, and the interior of which is used for arranging the stator assembly 500 and the rotor assembly 200. The stator assembly 500 is fixed on the inner wall of the housing 100, and the rotor assembly 200 is rotatably disposed at an inner side of the stator assembly 500. The shaft 210 is a component of the rotor assembly 200; when the motor is used, the rotating shaft 210 rotates and converts the electric energy into mechanical energy to output.
The heat dissipation fins 110 may be provided in a sheet shape, and may be provided in an axial section of the housing 100, that is, a section passing through an axis of the housing 100. The heat dissipating fins 110 may be integrally formed with the housing 100, connected to the housing 100 along one side in the radial direction of the housing 100, and may be formed in a wave shape or a straight line shape along the other side in the radial direction of the housing 100. In the present embodiment, the heat dissipating fins 110 are provided in a wave shape on a side of the casing 100 away from the casing 100 in a radial direction of the casing 100. Through the heat dissipation fins 110, the contact area of the housing 100 with air can be increased, so as to enhance the heat dissipation effect.
As shown in fig. 1 and 2, a plurality of heat dissipation fins 110 may be disposed at equal intervals along the circumferential direction of the casing 100 to surround a plurality of heat dissipation channels 120 equal in number to the heat dissipation fins 110. And, at both ends of the case 100, one fan 300 is provided. The fan 300 is sleeved on the rotating shaft 210, and forms a circumferential rotation limit with the rotating shaft 210, for example, the fan 300 and the rotating shaft 210 are connected by a spline or other structures, so that the rotating shaft 210 can drive the fan 300 to rotate synchronously when rotating; when the fan 300 rotates, it may drive ambient air into the heat dissipation channel 120, so as to enhance the heat exchange efficiency between the casing 100 and the air, and further improve the heat dissipation effect of the motor. Meanwhile, the two fans 300 drive the air to enter the heat dissipation channel 120 from the two ends of the heat dissipation channel 120, and the air can form convection in the heat dissipation channel 120, so that the heat exchange effect between the housing 100 and the air can be further improved.

It can be understood that, by providing the heat dissipation fins 110 on the housing 100 of the motor to form the heat dissipation channel 120, firstly, the heat of the motor can be transferred to the air through the heat dissipation fins 110 to form a primary heat dissipation; two fans 300 are arranged at two ends of the rotating shaft 210 to drive air to enter the heat dissipation channel 120 in opposite directions, and then the heat exchange effect between the heat dissipation fins 110 and the air can be improved in an air convection manner to improve the heat dissipation effect of the motor, and meanwhile, the heat of the motor can be conducted to the middle part of the shell 100 in a centralized manner; the heat conduction member 400 is disposed in the middle of the casing 100, so that heat of the motor is dissipated through the heat conduction member 400, and the heat concentrated in the middle of the casing 100 can be further transferred to the environment through heat conduction.
In summary, the heat dissipation motor provided by the application increases the way of heat dissipation of the motor to the environment, and can reduce the heat transferred from the motor to the air, so as to improve the cooling effect of the air on the motor, and especially, when the rotating speed of the motor is high or the motor works for a long time, the effect is remarkably improved; simultaneously because heat-conduction is faster for the heat radiation heat transfer, consequently this application can also improve the heat exchange efficiency of the totality of motor and environment, and then further improves the heat transfer effect of motor.
Specifically, the heat conduction member 400 includes a conductive base 410 and a flexible conductive tape 420, the conductive base 410 being connected with the case 100, one end of the flexible conductive tape 420 being disposed on the conductive base 410, and the other end extending in a direction away from the case 100.
As shown in fig. 2 and 3, in the present embodiment, it is exemplarily illustrated that the conductive base 410 and the flexible conductive tape 420 may be made of a material having a relatively good thermal conductivity, for example, the conductive base 410 may be made of a metal material. The conductive base 410 may be coupled to the case 100 by a bolt member to transfer heat of the motor. And a flexible conductive tape 420 may be coupled to the conductive base 410 to further dissipate heat. An end of the flexible conductive tape 420 remote from the conductive base 410 may extend to the ground or the refrigerant storage device, etc. in a direction away from the housing 100.
It can be understood that, in the present embodiment, by providing the heat conduction member 400 as the conduction base 410 and the flexible conduction band 420, it is easy to connect the flexible conduction band 420 with the housing 100 of the motor, and it is convenient to arrange the flexible conduction band 420 when extending it so as to extend it to the ground or the refrigerant storage device, etc., thereby effectively guaranteeing its function of transferring heat.
More specifically, the conductive base 410 is made of copper, the flexible conductive tape 420 is a copper woven soft tape, and the flexible conductive tape 420 is hinged on the conductive base 410.

The materials of the conductive base 410 and the flexible conductive tape 420 may be reasonably selected based on actual needs. The flexible conductive tape 420 may be hinged to the driving base by a hinge shaft so as to be rotated.
It can be understood that, in the present embodiment, the conductive base 410 is made of copper material, and the flexible conductive tape 420 is made of copper woven soft tape, so that the heat conduction effect of the flexible conductive tape 420 can be ensured when the conductive base 410 is arranged and the flexible conductive tape 420 is extended.
More specifically, the conduction bases 410 are disposed in the heat dissipation channel 120, and two conduction bases 410 are disposed, and the two conduction bases 410 are disposed on both sides of the flexible conduction band 420 in the axial direction of the housing 100, respectively, and the conduction bases 410 include a connection portion 411 and a guide portion 412, the connection portion 411 being connected to the housing 100, and the guide portion 412 being connected to the connection portion 411 and extending in the radial direction of the housing 100.
As shown in fig. 2 and 3, in the present embodiment, it is exemplarily illustrated that two thermally conductive bases 410 are each disposed between two heat dissipation fins 110, that is, within the heat dissipation channel 120, in the circumferential direction of the casing 100. And the flexible conductive tape 420 may be disposed between the two conductive bases 410 in the axial direction of the housing 100. The conductive base 410 may be a unitary member, i.e., the connection portion 411 and the guide portion 412 may be integrally formed. The connecting portion 411 may be an arc-shaped sheet to better adhere to the housing 100 of the motor, thereby effectively removing heat; and the guide part 412 may extend in a radial direction of the housing 100 and be connected to one end of the guide part 412 such that the conductive base 410 has an "L" shape. The two conductive bases 410 may be disposed opposite to each other, that is, the connection portions 411 of the two conductive bases 410 may be adjacent to each other. The hinge shaft of the flexible conductive tape 420 may be provided on the connection portion 411 of the two conductive bases 410.
It can be understood that the present embodiment is easy to connect the flexible conductive tape 420 with the driving base by providing the driving base in two and providing the conductive base 410 as the connection portion 411 and the guide portion 412; meanwhile, the guide parts 412 of the two conduction bases 410 can block air in the heat dissipation channel 120, so that the air is far away from the casing 100 along the radial direction of the casing 100, and further the purpose of taking away heat of the motor is achieved, and the air far away from the casing 100 along the radial direction is difficult to be re-driven by the fan 300 to circulate to the heat dissipation channel 120 again, so that the cooling effect of the air of the environment on the motor is guaranteed.
Specifically, the heat dissipation motor further includes two fan housings 600, the two fan housings 600 are respectively in one-to-one correspondence with the two fans 300 and are respectively connected to two ends of the housing 100, the fans 300 are disposed in the fan housings 600, air passing openings 610 are disposed on the fan housings 600, and the air passing openings 610 are communicated with the heat dissipation channel 120 along the inner sides of the fan housings 600.
As shown in fig. 1 and 2, in the present embodiment, it is exemplarily explained that the wind shield 600 may be open at one end and closed at the other end, and the open end of the wind shield 600 may be connected to the case 100 and the closed end may extend in a direction away from the case 100. The two wind hoods 600 are respectively disposed at two ends of the housing 100 and respectively cover the two fans 300. The air inlet 610 may be opened along an axial section of the casing 100, and several air inlets may be equally spaced along a circumferential direction of the casing 100. When the fan 300 rotates, ambient air may enter the wind shield 600 from the air inlet 610 and enter the heat dissipation channel 120 along the inner side of the wind shield 600.
It can be understood that, in the present embodiment, by providing the wind shield 600 and providing the air inlet 610 on the wind shield 600, the fan 300 is easy to suck ambient air to take away heat of the motor.
More specifically, the heat dissipation motor further includes a fixing frame 700, a first flange 620 is disposed on the fan housing 600, second flanges 130 are disposed at two ends of the housing 100, and the first flange 620 is connected to the second flanges 130 and disposed on the fixing frame 700.
As shown in fig. 1 and 2, in the present embodiment, it is exemplarily illustrated that the first flange 620 and the second flange 130 may be integrally formed with the wind shield 600 and the casing 100, respectively, and may be radially distant from an axis of the wind shield 600 or the casing 100. The first flange 620 and the second flange 130 may abut each other and be detachably coupled by bolt members. The fixing bracket 700 is used to fix the first flange 620 and the second flange 130, and an outer contour of a cross section of the fixing bracket 700 in an axial direction may be larger than outer contours of cross sections of the fixing bracket 100 and the wind shield 600 in the axial direction.
It can be understood that, in the present embodiment, the wind shield 600 is connected to the housing 100 by the first flange 620 and the second flange 130, and is fixed by the fixing frame 700, and an additional end cover may not be required. In this embodiment, the rotating shaft 210 may be rotatably disposed on the wind shield 600. And the structure of cancelling the end cover can reduce the hindrance that the air received in the inside of motor to make the circulation of air more smooth and easy, the radiating effect of motor further promotes. By providing the fixing bracket 700, the motor can be more easily arranged and can be conveniently kept stable.
More specifically, the fixing frame 700 includes an upper frame body 710 and a lower frame body 720, the upper frame body 710 and the lower frame body 720 are arranged in an involution manner and detachably connected, and the upper frame body 710 and the lower frame body 720 clamp and fix the first flange 620 and the second flange 130.

It can be understood that when the air enters the inside of the wind shield 600 through the wind passing opening 610, the air may further enter the heat dissipation channel 120 through the wind shield 600 to circulate to the outside of the housing 100 of the motor through a short path, and excessive energy loss caused by the circulation of the air is avoided, which reduces the heat exchange efficiency.
More specifically, the inside of the wind shield 600 extends in a flared shape in a direction approaching the casing 100.

Example 2:
the second embodiment of the present application provides a heat dissipation motor, which is different from the first embodiment at least in the heat conduction element 400.
Specifically, the conduction base 410 is made of copper material, the flexible conduction band 420 is a hollow tube band, a refrigerant is circularly arranged in the flexible conduction band 420, and a heat exchange surface is formed at the joint of the flexible conduction band 420 and the conduction base 410.
